Application of vacuum system in oil deacidification processing

2022-01-10

The following focuses on the application of vacuum system in oil deacidification processing, for your reference. Unrefined crude oils contain some amount of free fatty acids, and the process of removing free fatty acids from oils is called deacidification. The methods of deacidification include alkali refining, distillation, solvent extraction and esterification. Among them, the most widely used are alkali refining and distillation. Distillation deacidification method is also known as physical refining method, that is, the free fatty acid in crude oil is not neutralized by alkalis, but a refining method for deacidification by vacuum steam distillation. The distillation deacidification method usually uses a steam jet vacuum pump to achieve vacuum. This method needs to consume a lot of water vapor, so the water consumption is high, and a large amount of waste condensate will be formed, resulting in a slippery production site and a hot and humid working environment. Potential Security risks.

The blister machine is a machine that absorbs the heated and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils into various shapes of packaging boxes, boxes and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened PVC, PET and other thermoplastic plastic sheets are blistered into various shapes of vacuum covers, blister trays, blister shells, etc.

Precautions for vacuum pump disassembly and cleaning for vacuum pump maintenance

A vacuum pump is a device that uses various methods to generate, improve and maintain a vacuum in a closed space. A vacuum pump can be defined as a device or device that uses mechanical, physical, chemical or physical-chemical methods to pump the container to obtain a vacuum. Any pump that uses mechanical motion (rolling or sliding) to obtain vacuum is called a mechanical vacuum pump. After a period of use, the vacuum pump needs maintenance, and cleaning the vacuum pump is one of the things that needs to be done. Some vacuum pump users ask a question, what are the precautions for vacuum pump disassembly and cleaning for vacuum pump maintenance?

Features of vacuum pump

(1) Larger pumping speed in a wider pressure range;(2) The rotor has good geometric symmetry, so the vibration is small and the operation is stable. There are gaps between the rotors and between the rotors and the casing, no lubrication is required, and the friction loss is small, which can greatly reduce the driving power, so that a higher speed can be achieved;(3) The pump cavity does not need to be sealed and lubricated with oil, which can reduce the pollution of oil vapor to the vacuum system; (4) There is no compression and no exhaust valve in the pump chamber. Simple and compact structure, insensitive to dust and water vapor in the pumped gas; (5) The compression ratio is low, and the effect of hydrogen pumping is poor; (6) The surface of the rotor is a curved cylinder with a complex shape, which is difficult to process and inspect.
